Abstract
Disclosed is an ostomy device with an adhesive wafer for attachment to a skin surface (S) of a user and a collecting bag (8) or collecting output from a stoma. The collecting bag is connected to the adhesive wafer, and the adhesive wafer has a through-going hole (6) for accommodating the stoma (7) of the user. The adhesive wafer includes a backing layer (3), a first switchable adhesive composition (2), a second absorbent adhesive composition (1), and a release liner, and the second adhesive layer has a central portion with a first thickness and an edge portion with a second thickness, the first thickness being larger than the second thickness.
Claims13
An ostomy device providing a hole adapted for placement around a stoma of a user, the ostomy device comprising:
- an adhesive wafer having a backing layer, a switchable adhesive layer applied to the backing layer, wherein the switchable adhesive layer is non-skin facing, and an absorbent adhesive layer applied to the switchable adhesive layer, where the backing layer defines a distal surface of the ostomy device and is adapted to receive a collecting bag for collection of output from the stoma;
- wherein the hole is sizable to receive a stoma and is formed through the backing layer, the absorbent adhesive layer, and the switchable adhesive layer;
- wherein the switchable adhesive layer is a ring-shaped annular band having a lateral extent that extends from an edge of the hole to an outermost perimeter of the ostomy device and the absorbent adhesive layer is formed around an entirety of the hole and extends from the edge of the hole to a rim that is located a radial distance away from the edge of the hole, where the radial distance is less than the outermost perimeter of the ostomy device;
- wherein the switchable adhesive layer covers the entirety of the surface of the absorbent adhesive layer;
- wherein the absorbent adhesive layer has a first thickness measured at the edge of the hole and a second thickness measured at the rim, and the first thickness is larger than the second thickness;
- wherein the switchable adhesive layer comprises a photoinitiator reactive to visible light;
- and
- wherein the absorbent adhesive layer includes absorbent particles distributed throughout the absorbent adhesive layer.
